Hi everyone,
I installed the latest versions of WordPress and BuddyPress. However, when I try to use the search and private message on the site, I am faced with this error:

0

Found

The document has moved here.

Additionally, a 302 Found
error was encountered while trying to use an ErrorDocument to handle the request.
